C-Vaccinating using injection
D-vaccinating by feather follicle
E-Vaccinating in ovo injection
1-Mass vaccination :
A-vaccination via drinking water
Most commonly used in field it produces very good results is ideally administrated early in morning this is peroid when the birds are active in term of drinking
*the water must be clean and fresh free from suapended organic substances and bacteria have PH=5.5 to 7.5

2-individual vaccinations
A-vaccinating by eye drop ,nasal drop, oral drop
Is one the most effective techniques it ensures that a complete dose is administered to each bird
B-vaccinating by wing web
The vaccine is applied to birds by transfixing the internal face of the wing membrane using a double or single needle which had previously dipped in the vaccine solution
C- Vaccinating using injection
Vaccination via subcutaneous (SC) or intramuscular (IM)
SC injection are given in to the base of neck
IM injection are given into thigh or muscle around sternum
D- Vaccinating by feather follicle
Use for administeration of Fowl Pox vaccine by removing feather from area of vaccination on the thigh and applying the vaccine by use brush
E- Vaccinating in ovo injection
Injection of vaccine in eggs for purpose of vaccinating the embryo before hatching for giving the chick strong immunity in first period of it's live
Failure of vaccine
*use of expired vaccine
*genetic resistence
*improper strorage of vaccine
*health status of the flock
*immuno suppression due to drugs
*mycotoxins
*water deprivation and heat stress
*cold and high density stress
*poor nutrition
*presence of ammonia in houses
*poor antigenicity of vaccine
*maternal antibody.
